Being insulted by someone else’s opinion is never based on one thing. Whenever you’re feeling insulted, take an account of all the factors playing into the insult. How much of being insulted by someone else’s opinion is determined by your own opinions and expectations?
Answering this question takes you a long way towards feeling less insulted when you walk into an insulting situation. Feeling insulted is not a resourceful state, and you’re more likely to do unproductive things from a state of being insulted.
Do no harm. Take no sh*t.
